摘要：
Blue Compact dwarf galaxies are young starburst dwarf galaxies. A morphological classification has been proposed in the early 80's based on the Hubble sequence. On one hand, the classification resembles the one of the normal galaxies: elliptical-like and irregular-like. It was thought that the morphology reflects the dynamics. BCDGs shall be rotation supported and claims for 'spiral arms' have been made. On the other hand, recent observations both in the IR and optical ranges suggest that the structure of BCDGs is more complex, probably the results of mergers, and/or slow accretion.
